HOLDING CLIP ,FOR CGNCRETE REENFORCEMENT;

.Appncanm filed December 25,11923. Serial no; esavev.

The invention relates to certain new-and useful improvements inholdingclips for concrete reenforcement- A One of the objects of theinvention-is to rovide an improved mesh spacer or wire chair forsupportingthe reenforcing structure of concrete members, especially inperpendicular surfaces, before the cementitious material is applied tothe same, and before it is set. I Y

Anotherobjectis to provide a combined supporting and spacing means forconcrete reinforcements, where the, concrete'is distributed by a cementgun; and one thatavill be completely filled up with the cement.

A further object is to furnish a simple mesh spacer constructed entirelyof metal wire that can be easily and quickly fastened to the supportingmember by a common nail or the like.

A still further object is to provide a spacer that can be compressed, orknocked down,

from its normal height while itis being placed in position, so thatpractically any depth of reenforcement may be made by one size of clip.

With these various objects in View, my invention consists of the novelfeatures of construction, combination and arrangement of partshereinafter fully described, pointed out in the claims and shown in theaccompanying drawings in which similz have similar numerals of referenceattached thereto:

Figure 1 is a side elevation of the preferred embodiment of theinvention.

Fig. 2 is a front elevation.

Fig. 3 is a top plan View.

Fig. 4 shows the mesh spacer in position.

Referring now to these drawings, 1 represents my improved wire chair ormesh spacer which comprises, when positioned as more.

particularly shown in Fig. 4, a horizontally placed U or loop 2, merginginto two vertically placed Us or loops 3 and a, one on each side of thesaid first mentioned loop 2. The continuation 5 of the loop 3, and thecontinuation 6 of the loop 1 then extend horizontally and practicallyparallel; the right hand one 5 extending forward to about the furtherend of the horizontal loop 2, then perpendicularly downward as at 7 tothe floor 8, and then backward as at 9 to about the outer periphery ofthe right hand 11' parts vertical loop 3, but spread to the right. Theleft hand horizontal portion'ti extends for: ward horizontally, butonlyfor a'shortdis tance bending abruptly backward and d'iagonally downwardas at 10 to the'floor, and

' then extending forward as at 11 to about the same length as the righthand leg or member 9. This leg9 is also bent sideways to the: left, thetwo legs being spread apart about equally, as shown more part cularly 1nFig.2.

In operating thejinvention, the reenfoi'cing members as 12 are placedover the temporary wooden backingglilw, and are held in place by myhereindescribed mens ear-,1,[o epr the said recnforcing members beingshown in Fig. a partly encircled by the two side by side vertical Us orloops 3 and 4. ,A common nail 1a or screw or the like, is then insertedthrough the upper loop 2 and driven into the backing of wall,- floor orceiling. The reenforcement now being held in position ceinentitiousmaterial or the like is either laid over and between the said mem bersmanually or'by the well known cement liquid or plastic material willfill up all around the mesh spacer in every direction, as there are nofiat parallel sides into which the material might-not, and often doesnot run.

Instead of requiring several sizes of clips for different thicknesses ofreenforcement as with other chairs, one size will do. For the nail canbe driven into the wood backing more and more, spreading the legs 7 and10 further and further apart and thus reducing the height of thereenforcing members 12 from the backing 13.

If the entire wall, floor or ceiling had been overlaid by thereenforcing members to a certain height from the backing and thecementitious material had not yet been laid, and it were desired to havesaid height from the backing less, all of the nails in place could bedriven in still further and the legs 7 and 10 spread further apart as at15, Fig. 2, and the whole set of reenforcing members would be pusheddown thereby nearer'the backing.

This mesh spacer can also be made up in large sizes for concretereenforcing bars,

mally lies over the top of the reenforcing bar, down over the same, asat 16 in Fig. 1, and this will hold the bar tightly in place and therewillbe no shitting or turning over, as is liable to happen in otherchairs.

As my invention is in some of its aspects generic, I do not limit myselfto the details as shown and described, but also contemplate theemployment of suitable equivalents that ltairly fall within the scope ofmy claims.

In this connection I may state that I may 'niake the two forwardlyextending members 5 and 6 of the same length, and the loops 2, 3 and ismaller if desired.

Therefore it will be understood that I may make various changes in thedetail, form, size and proportion as well as the number and position ofthe several parts, without departing from the spirit of the invention.

I claim:

1. A mesh spacer comprising a single piece of wire having a horizontalloop, two contiguous vertical loops, and a leg depend ing from each' ofthe said last mentioned loops, one of the said legs having a footpointing forward and the other leg having a foot pointing backward.

2. A mesh spacer comprising a single piece of wire having a horizontalloop, two contiguous-vertical loops, a leg portion eX- tendingdownwardly from one ot the last mentioned loops, a portion extendinghori- Zontally trom'the other of said loops, a leg portion extendingdownwardly from the end of said horizontal portion, and foot porionsextending horizontally in opposite directions from the ends of said legportions.

3. A mesh spacer comprising a single piece of wire having threecontiguous open loops, two of said loops being arranged in planessubstantially parallel with each other and substantially perpendiculartothe plane of the third loop, leg members extending from each of thetwo first/mentioned loops in directions away from the third loop, andfoot portions at the ends of said leg members and lying in a planeparallel with the plane of the third loop.

In testimony whereof I hereby affix my signature.
